#5514S- Innovations - Set of 5

America has long been a worldwide leader in exploring new frontiers and pushing boundaries. Today's frontiers are more than ever scientific and technological in nature to improve our lives. The five stamps in this INNOVATION set recognize American ingenuity, spirit, and inventiveness in five scientific fields: computing, biomedicine, genome sequencing, robotics, and solar technology. Most of the fields in this set have not been recognized on a stamp until now. Each stamp design has a bold graphic design for its field. Scott 5514-18 Innovations
